    Identify this locker

    I think this may be a LockRight but not sure. It's a GM 14 bolt SF I picked up from the junk yard. The junk yard owner said he was told it was a GM g80 diff but think it may be better. I was having trouble finding 3.42 rear end so I snatched it up. Turns out that the left tube it rusted at the...

    Alternator/truck wiring

    Perhaps someone can answer a question about alternator and wiring. I have a 97 K1500 truck as well as a 99 K1500 and K2500 suburban. The two suburbans have a junction/fuse block on the radiator shroud where the power wire comes from the driver's side and then the wire from the alternator joins...

    Rough running 7.4 Vortec

    Hi all, I recently picked up a 99 2500 Suburban with a 7.4 Vortec. I bought it knowing it has some issues. But the frame and body are great so a few problems can be fixed. The big problem is she runs rough. Has a rough idle, starts a little hard at times and has some valve train noise. I'm...

    7.4L intake gaskets

    I know plenty about the 5.7 and the history with intake gasket issues. I even did them on my 97 K1500. But, I know nothing about the 7.4L vortec. I'm looking at a 99 K2500 Suburban that is using coolant. Do these things have similar intake gasket issues? If that's likely the issue it doesn't...

    When working on my 97 ecsb k1500 I put overload /add a leaf springs in the rear to fix the sagging springs. I can't seem to find any for the suburban.

    98/99 4l60E Deep VS Shallow Pan

    I'm getting ready to swap transmissions in my 99 Suburban. The tranny is coming out of a 98 K1500 truck and has a shallow pan. My current tranny has a deep pan. Can I just swap the shallow for the deep pan? I'm assuming there is no difference between the transmissions beside the pan depth. The...

    Plastic fan vs metal fan

    While doing the water pump on my 97K1500 I wondered when GM switched to a plastic cooling fan. My truck has the metal fan but I've seen some with the plastic fan. Which is better? Does it even matter?

    Aux/CD player connection

    I have a 97 K1500 ecsb. The radio has the add on CD player. I haven't taken anything apart but am curious as to the wiring from the CD player to the radio. Is it a flat cable or separate wires? I am curious as to whether there is a possibility that I could take the CD player out of the system...

    4wd selector switch

    I'm trying to verify something I read once but can't find again. I had read that if the 4wd pushbutton switch messes up the truck will default to 4 high. Sounds odd to me. The reason I ask is my 4wd switch doesn't always work. The light will flicker and it won't work until I tap the switch. I'm...

    Bolt on helper springs

    I know it is not ideal to use bolt on helper springs but I was wondering if anyone has used them with success. I have a 97 ECSB 4WD with a sagging rear end. It is winter, cold and snowing most of the time so I was looking for something cheaper to take the sag out until I can attack the leaf...

    97/99 side mirrors

    First off, I have a 97 ECSB K1500 5.7 Auto. It has power mirrors but the driver's side mirror does not adjust properly. I had acquired complete doors off a 99 Tahoe so I pulled the driver's side mirror off to put on my 97. What I discovered is that the 99 had an 8 wire plug while my 97 has a 4...

    Z71 package original equip. tires.

    I have a 1997 ECSB 4wd Z71. I read somewhere that Z71 trucks came equipped with 265/75/16 tires. Is this true? My door sticker is long gone but the RPO codes show mine came with LT245/75/16 tires. RPO codes also show it is a Z71.

    Headlight pins/bolts

    I have 97 K1500 extra cab short bed Silverado trim that I bought about a month ago. I'm slowly going through things to make sure it is working properly. The truck has 206k on it with a little rust and runs great. So, today I tried to remove the headlights so I knew how to actually change a...
